Most of the enamel additives used for enamel slurry mixing are electrolytes that are easily soluble in water, and are used as saturated solutions. Today we will introduce the role of common enamel additives such as borax, urea, sodium nitrite, and magnesium sulfate in the enamel slurry, which is convenient for enamel factories to apply in the actual operation process.
Magnesium Sulfate (MgSO4•7H2O): Retaining agent for ground coat, titanium enamel and color enamel. Excessive amount will reduce the staying effect, and will cause the porcelain surface to be rough and reduce the adhesion.
Barium chloride (BaCl2•2H2O): The retention agent of antimony enamel, titanium enamel and colored enamel, it is difficult to handle if the excessive consistency is large, but it is forbidden to use bright red and cadmium yellow.
Potassium carbonate (K2CO3): Titanium enamel retention agent, excessive amount will cause piping watermarks, yellowing, and serious boiling.
Sodium carbonate (Na2CO3): Solve the pitting of the ground coat layer, the bullet points and small black spots of the surface enamel layer, and excessive amount will cause the enamel slurry to stay poorly.
Potassium Chloride (KCL): A retention agent for titanium enamel, excessive amount will cause piping watermarks, yellowing, and serious boiling.
Sodium Chloride (NaCl): Used for surface enamel, it can increase the strength of powder blank, and excessive amount will affect the gloss of porcelain surface.
Borax (Na2B4O7•10H2O): Solve the pitting defect of the ground coat layer, and excessive amount will easily cause boiling or shrinkage.
Urea (NH) 2CO: Increase the strength of the enamel powder blank, and solve the defects such as powder lines, black lines of piping watermarks, and black spots. Excessive amount will reduce the physical and chemical properties of enamel products (gloss, acid resistance, heat resistance, impact resistance) and cause boiling defects, so red enamel paste should not be used.
Sodium nitrite (NaNO2): Solve the yellow rust spots caused by poor drying of the ground coat powder. Excessive amount can easily cause piping watermarks, blistering or boiling.
Potassium chlorate (KClO3): Solve the boiling point of the titanium enamel layer. Excessive amount will reduce the luster and cause the edge watermark to boil. The enamel products with red edge enamel should be added less to avoid darkening the edge enamel color.
Sodium chlorate (NaClO3): The effect is the same as that of potassium chlorate.

What is KNO2?
Potassium nitrite (KNO2) is a chemical compound composed of potassium and nitrite ions. It is used in various industrial processes, such as in some pyrotechnic devices and as a food additive. It is also known for its role in organic chemistry reactions.
What life form can change toxic ammonia into nitrate?
Certain bacteria, specifically nitrifying bacteria, can convert toxic ammonia into nitrate through a process called nitrification. This process involves two main groups of bacteria: ammonia-oxidizing bacteria (AOB), which oxidize ammonia to nitrite, and nitrite-oxidizing bacteria (NOB), which further oxidize nitrite to nitrate. These bacteria play a crucial role in the nitrogen cycle, helping to mitigate the toxicity of ammonia in the environment.
Bacteria in the soil which turn nitrite into nitrate are called?
Bacteria that convert nitrite into nitrate are called nitrifying bacteria. These bacteria play a key role in the nitrogen cycle by facilitating the conversion of ammonia into nitrite and then into nitrate, which can be taken up by plants as a source of nitrogen for growth.
What is sodium main function?
Sodium plays a crucial role in maintaining fluid balance in the body, regulating blood pressure, and supporting muscle and nerve function. It also helps with nutrient absorption and transportation in the body.
What are nitrifyers?
Nitrifiers are a group of bacteria that play a crucial role in the nitrogen cycle by converting ammonia into nitrates and nitrites, which are usable forms of nitrogen for plants. This process, known as nitrification, occurs in two main steps: first, ammonia-oxidizing bacteria (AOB) convert ammonia to nitrite, and then nitrite-oxidizing bacteria (NOB) convert nitrite to nitrate. Nitrifiers are essential for maintaining soil fertility and are commonly found in soil and aquatic environments. Their activity helps mitigate the toxicity of ammonia and supports healthy plant growth.
What is the role of nitrosomonas and nitrabactor in nature?
Nitrosomonas converts ammonia into nitrite in the nitrification process, while Nitrobacter converts nitrite into nitrate. Both are essential in the nitrogen cycle, converting various forms of nitrogen to make it available to plants for growth.
What is the role of sodium borate in the interaction between polyvinyl alcohol and other substances?
Sodium borate, also known as borax, acts as a crosslinking agent in the interaction between polyvinyl alcohol and other substances. It helps to form strong bonds between the polymer chains of polyvinyl alcohol, increasing its strength and stability. This crosslinking process is important in various applications such as adhesives, coatings, and films.
What is an explosive substance which is an common preservative?
An explosive substance that is also a common preservative is sodium nitrate. It is often used in food preservation, particularly in cured meats, to inhibit bacterial growth and enhance color. However, sodium nitrate can decompose under certain conditions to form explosive compounds like sodium nitrite and nitrous oxide. While it serves a vital role in food safety, its dual nature as a potential explosive highlights the need for careful handling.
What is the main four elements of seawater?
The main four elements of seawater are hydrogen, oxygen, sodium, and chlorine. Hydrogen and oxygen combine to form water (H2O), which makes up the majority of seawater. Sodium and chlorine combine to create sodium chloride, or table salt, which is the primary salt found in seawater. These elements are essential for marine life and play a significant role in ocean chemistry.
What is the roll of borax in making the polymer?
Borax plays the role of a cross-linking agent in making polymer slime. It forms cross-links between the polymer chains, which helps to give the slime its unique stretchy and squishy properties.

Is nitrogen in the form of ammonia nitrate and nitrite is found in the soil?
Yes, nitrogen can be found in the soil in the form of ammonia, nitrate, and nitrite. These compounds serve as important nutrients for plants, supporting their growth and development. Soil bacteria play a key role in converting organic nitrogen into these forms that are accessible to plants.
